HAY-TEDDER.

SPECIFICATION forming part of Letters Application filed January 13. 1885.

Patent No. 339,742, dated April 13, 1886.

Serial No. 152,768. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL R. COLLIER, of Xenia, county of Greene, State of Ohio, have invented new and useful Improvements in Hay-Tedders, of which the following is a full and exact description, reference being had to the accompanying drawings, making part of this specification.

This invention has relation to hay-tedders; and it consists in the construction and novel arrangement of devices for throwing the op erating mechanism into and out of gear, as will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure l is a perspective view of that portion of a haytedder that is necessary to illustrate my in vention; Fig. 2, an elevation and plan view of the shipping device detached from the machine. Fig. 3 is a side and plan view of the side plate or box in which the oblong opening is formed to receive the axle-box; Fig. 4, an elevation and plan view of the axle-box. Figs. 5 and 6 are side and top views of the arms for connecting the axle and side plates. Fig. 7 is a side and edge view of the shipping-lever, and Fig. 8 is a side and edge view of slotted plate with which the shipping-lever engages.

Referring by letter to the accompanying drawings, 0 designates the side plate or box, which is provided with flanges C, for securing the same to the outer side of the frame or rail J. The opening in this side plate or box extends entirely through the same, being preferably made oblong in form, and is adapted to receive a box, I), in which the axle box or plate 0 slides. This box I) is of the same width as the opening in the plate or box 0, but is made shorter, so that while all ve'tical' movement is prevented it is free to move longitudinally therein, and said further provided with flanges 1- r, for .1 ing the inner face of the plate to preveit any outward displacement thereof. This box I) is also provided with a cylindrical opening in the center for the passage of the axle a.

Arms d and 6 connect the axle and side plate together, and said arms are provided with shoulders O O, and are hinged together by the rivets the arm cl being rigidly secured to axle a by means of a rivet, bolt, or

set-scre\v, and arm 0 being provided with a circular opening, which is slipped over the stud p on plate 0, the whole forming a togglejoint. When the hinge thus formed is extended and its several pivotal points are in a straight line, as shown in Figs. 1 and 2, the shoulders 0 0, engaging with each other, prevent the joint from passing below the center and forming a complete lock-lever.

I represents a section of the main drivinggear, which is bolted to the inner side of the ground or carrying Wheel of the machine, and from which motion is communicated to a pinion, h, mounted on the main frame or rail J to the cranks Z.

In Fig. l the pinion h is shown as being in gear with the drivinggear I, the axle a passing through the box b to receive the ground wheel, to which said gear I, as before stated, is attached. When the machine is thus in gear, the arms (Z and e are extended, forcing the box b forward in the box or side plate, 0, and forcing the box 0, and with it the main frame, backward or away therefrom, and said parts being firmly held extended or locked in this position by the toggle-arms d and e, as before described, and effectually preventing the pinion from being forced out of gear when the tedder is in heavy grass or the forks encounter some opposing obstacle and the driv ing mechanism as a consequence placed under great strain.

To provide an additional holding device to prevent the gear from being accidentally unshipped or to prevent the toggle-arms being thrown out of lock by a sudden jar of the machine, a shipping lever, g, is rigidly secured to the axle about cent-rally of itslength, which engages through aspring-bolt, s, with a lug, q, formed on a plate, f, secured to the central frame -bar, Ir, which prevents any movement or rotation of the axle. This central plate, f, is provided with an oblong opening through which the axle passes, and said plate being firmly secured to the central bar, It, serves as an additional or central support for the axle.

In the drawings the central plate is shown as provided with a lag, q, with either end of which the spring-bolt s is engaged to hold the lever locked in either of its positions; but if desired, however, a notch may be formed in the upper face of the plate at each end with which the lever may engage.

From the foregoing description of the construction and operation of the device to hold the driving-mechanism in gear, it will be readily understood that when it is desired to disengage the gears it will only be necessary to thrust the lever 9 forward and cause the rotation of the axle a, which will raise the link (i and unlock the toggle, as shown in dotted line, Fig. 2. \Viththis movement plate 0, with frame J, is carried forward 011 box I) sufficiently to disengage pinion h and gear I and stop the motion of the machine. The shipping-lever 9 thus thrown forward, and the machine being out of gear, is held in this position by the spring'bolt s engaging the forward end of lug q or with the forward notch.

hen the machine is in gear, lug m on arm (I engages with the corresponding lug, a, on sliding box 1), thereby relieving the togglejoint from strain. Similar boxes and connecting-arms are used on both sides ofthe machine.

From the foregoing description and by reference to Fig. 1 it will be readily understood that the entire frame of the machine is carried upon boxes I) b, having their bearings in plates 0 G, and that the method of shipping the machinery into and out of gear is by moving the frame bodily forward or back ward in astraight line, and which is accomplished by a slight thrust of the lever g in the manner described.

Parts of the machine not particularly described may be constructed in any usual or preferred way.

I am aware that it is not new to move the pinion out of mesh with the driving mechanism by a forward movement of the frame, as shown in patent granted to Stetson, April 5, 1859, No. 23,508; but,

Having now described my invention, I claim 1. In a hay-tedder, the side plates connected to the sliding frame and provided with the openings to receive the boxes mounted upon the axle, in combination with the boxes fixed upon the axle, and mechanism for adjusting the frame fore and aft, whereby the crankshaft pinion' mounted on the frame may be thrown into and out of action with its driving mechanism by the backward and forward movement of the frame.

2. The side plates connected to the frame and having the openings formed therein, through which the axle passes, in combination with the short arms connected, respectively, to the frame and the axle, whereby the frame is moved forward or back 'by the rocking of the axle, sub stantially as and for the purpose set forth.

3. The lever-plate connected to the frame and provided with the slot or opening for the passage of the axle and with the lug or notches, in combination with the shipping-lever secured to the axle, and'adapted. to engage the lug or notches for holding the frame in either of its adjusted positions, substantially as described.

4. The combination of the side plates connected to the frame, and with the axle mounted therein, with the links for connecting thesame together, having the shoulders formed thereon, substantially as and for the forth.

5. The combination of the box, having the lug formed thereon, with the arms secured to the axle, and provided with a corresponding lug to engage the lug formed on the box when the driving mechanism is in gear, substantially as and for the purpose set forth.

6. In a hay-tedder, the combination of side plates, 0, boxes b, hinged arms d e, lugs m a,

lever g, and axle a, when arranged and oper ating substantially in the manner and for the purpose set forth.

In testimony whereof I have hereunto set my hand this 4th day of December, A. D.- 1884.
